Managing of Large Data Artifacts on Mobile Devices with an Ultra Sensitive GPS Devices

Nowadays there is decreasing number of limitations during using commercial mobile devices for data transfer, wireless connectivity or mobile device tracking. The last item is main area of this work. The model of a radio-frequency based system enhancement for user's location and tracking is developed for mobile information systems. The experimental framework prototype uses a few wireless technologies to determine indoor and outdoor position as wireless network infrastructure, global position system (GPS) etc. User location is mainly used for data prebuffering and preload by information system server to PDA or mobile device. All data on the server are saved with its artifacts as the position in the building or outdoor area and used location technology respectively. The reason for prebuffering is high speed of application response when a large amount of data is needed to transfer by server to mobile client.
